Sequential S3D is vanishing. Zspace uses it for their windows only apps.  Nvidia barely supports S3D as a technology. Not sure if any other chip makers are using sequential anymore.  Chip electronics have outpaced the need for sequential.



SBS half, the chimera DTI option output as HDMI is your best bet, regardless of the OS.  


Some of the Samsung tv/monitors that do hdmi 2.0 now offer SBS half at 4k.


This resolution is better than bluray S3D framepack under HDMI 1.4, and is probably the best you will get for the foreseeable future (ie, 5-15 years).

Subject: Re: [Chimera-users] Sequential stereo problems in Chimera in Mac after updating to OSX EL Capitan
 
Hi Peter,

  If Chimera says "Unable to find hardware stereo support  … “ when you enable sequential stereo it means the graphics driver does not support quad-buffered OpenGL stereo. Unfortunately Apple has not been interested in supporting stereo so I’m surprised you had it working recently.  For several years now no machines Apple sold supported stereo.  We had an ancient (8 year old) Nvidia Quadro FX 5600 in a Mac Pro until about 2 years ago, but the performance became so poor we abandoned it and had to switch to Windows.  The new Mac Pro cylinders did not support stereo.

  Unfortunately Apple also doesn’t seem to provide any information on which systems support stereo.  We used to be able to get this information from the Apple OpenGL Capabilities web page

  https://developer.apple.com/opengl/capabilities/
OpenGL version 1.5 - Apple Developer Tools
OpenGL Capabilities Tables. The following table lists OpenGL extensions and parameter values reported for each of the OS X versions, graphics adapters, and CPU ...


but they stopped updating that two Mac OS versions ago (10.9).  Now the only thing I can find from Apple about OpenGL support is this page

https://support.apple.com/en-us/HT202823

that lists the OpenGL version supported by each of their computers.  Quad buffered stereo is not a requirement of any OpenGL version so this page does not help find out about stereo support.

  With Mac OS El Capitan (10.11) Apple has talked a lot about “Metal” which is an alternative graphics programming interface.  Chimera does not use it since it is Apple only and we need to support Linux and Windows.

  In summary, I think Apple has dropped support for stereo on your systems.  Could you tell us what graphics card it was working with and which Mac OS version (Mavericks 10.10?).  Also if you use Chimera menu Help / Report a Bug… we will know the configuration that no longer works which will help us advise other Chimera users.

Tom

Hi,

No sequential stereo is working in Chimera after updating of our Macs to
OS X El Capitan -  10.11.1 in the CRTs linked to MacPros

Error remarks:
- unable to turn on stereo viewing - "Unable to find hardware stereo support  ... "

(see attachment).

This problem has not appeared in with earlier OSX updates!

We hope this problem will be fixed soon.

Cheers
Peter
